Numerous functions that adjustment program described below may be implemented, but adjustment program need not all implement following institute It is functional, it is only necessary to implement one of them or its any combination.
In one embodiment, adjustment program can search the touch-control processing unit 130 that main frame 140 is connected, and show One of following message or its any combination：Host interface form (such as USB or I2C), the kind of touch-control processing unit 130 The finger touch that class, form, firmware version number, version check code number, firmware manufacturer, firmware kernel version number, firmware are supported Number.
As shown in Fig. 2 it is the schematic flow sheet according to the search display methods of above-described embodiment.Step 210, institute is passed through Some host interfaces search touch-control processing unit 130.Then, in step 220, to all touch-control processing units 130 searched Send out information requirements.Finally, in step 230, receive and show the information of touch-control processing unit 130.
In one embodiment, adjustment program can set the audio communication output of main frame 140, to be sent in one of following situations Sound.Sound is sent when touch-control processing unit 130 has detected external conductive object or active pointers proximity touch control screen 120 Sound, and/or when touch-control processing unit 130 has detected external conductive object (such as finger) or active pointers stopping proximity touch-control Sound is sent during screen 120.Adjustment program can also set the frequency and/or length of sent audio communication, so that user makes During with adjustment program, the external conductive that knows for sure object or active pointers whether proximity touch control screen 120.
In one embodiment, adjustment program can match touch control screen 120 and touch-control processing unit 130.In an example In, can also profit when the screen number that adjustment program can be connected using the display control unit of connection come detecting host 140 The number of the touch-control processing unit 130 connected with the embodiment shown in Fig. 2 come detecting host 140.When screen or touch-control are handled The number of device 130 is more than for the moment, you can to implement the method for pairing.Due to and not all screen be all touch control screen 120, So the number of screen should be greater than or the number equal to touch-control processing unit 130.Therefore can be made in turn with adjustment program glimmering Curtain idsplay order, it is desirable to which user touches the screen of idsplay order.And in order to avoid the event of false touch, it may also require that user is defeated Enter complex gesture.After some touch-control processing unit 130 detects above-mentioned touch or gesture, it is possible to will be aobvious Show that the screen of instruction is matched with receiving the touch-control processing unit 130 of touch signal or gesture.Adjustment program can be to still Unpaired screen carries out identical instruction, untill all touch-control processing units 130 are paired.Certainly, also having can Energy touch-control processing unit 130 is not with the pairing of some screen, then adjustment program can be further in unpaired successful screen Display information.If user judges that a certain touch control screen 120 does not match with touch-control processing unit 130, you can learn the touch-control The touch control electrode of screen 120 is not connected to touch-control processing unit 130.
After being paired, in the information of foregoing shown touch-control processing unit 130, matched touch-control can also be added The information of screen 120, such as：Length and width dimensions, first electrode 121, the number of second electrode 122 or its derivative of touch control screen 120 Parameter.
In one embodiment, adjustment program can make touch control screen 120 show warning message, it is desirable to which user does not touch tactile Control screen 120.In this stage, adjustment program can make the hardware detection of the progress touch control screen 120 of touch-control processing unit 130.
Refer to shown in Fig. 3 A, it is the schematic diagram according to the touch control electrode linkage interface of one embodiment of the invention.Should Linkage interface includes touch control electrode joint 321 and touch-control processing unit joint 322.Before touch control electrode joint 321 may be coupled to The a plurality of first electrode 121 or second electrode 122 stated, in Fig. 3 A example, the touch control electrode joint 321 has collected 12 article One electrode 121.Touch-control processing unit joint 322 may be coupled to the touch control electrode interface of touch-control processing unit 130, Fig. 3 A's In example, the touch-control processing unit joint 322 has collected 20 touch control electrode interfaces.In other words, the touch-control processing unit 130 Design can at most connect 20 first electrodes 121, but in Fig. 3 A examples, touch-control that the touch-control processing unit 130 is connected Screen 120 only has 12 first electrodes 121.
When assembling electronic installation 100, assembly crewman may be by the first piece-root grafting of touch control electrode joint 321 at touch-control Manage device joint 322 first, form the misalignment shown in Fig. 3 A.Also i.e. by the first piece-root grafting of touch control electrode joint 321 To the 3rd of touch-control processing unit joint 322.What is more, and assembly crewman may do the direction of touch control electrode joint 321 Instead, Fig. 3 B situation is formed, is also the 14th by the first piece-root grafting of touch control electrode joint 321 to touch-control processing unit joint 322 Root, by the 3rd of the 12nd piece-root grafting of touch control electrode joint 321 to touch-control processing unit joint 322.In addition, also have a kind of possible It is the interface that the joint of first electrode 121 is connected to second electrode 122 by mistake, while the joint of second electrode 122 is connected to by mistake The interface of one electrode 121.These mistakes are all recurrent problems when electronic installation 100 assembles, and after once assembling, Adjustment program provided herein can be used for detecting at connection and the setting touch of hardware with touch-control processing unit 130 The inner parameter of device 130 is managed to adapt to the connecting staggered situation of hardware.
In one embodiment, after adjustment program makes touch control screen 120 show Do Not Touch, adjustment program can make tactile Control the step of processing unit 130 carries out electrode connection detecting.Because first electrode 121 and second electrode 122 have resistance value, when First electrode 121 or second electrode 122 are connected to, whether the resistance value that touch-control processing unit 130 can detect interface changes. Among Fig. 3 A and 3B example, touch-control processing unit 130 can detect the 3rd to of touch-control processing unit joint 322 The resistance value of 14 piece-root grafting pin changes.Therefore, it follows that first electrode 121 shares 12.Likewise it is possible to the second electricity Pole 122 carries out similar detecting, can also learn the quantity of second electrode 122, and the original position of the joint of its connection with End position.
Although the resistance value of this 12 first electrodes 121 is different, should fall within limits.If wherein have a certain The resistance value of root first electrode 121 is different from other, then can speculate that the first electrode 121 is broken or electrical contact is bad. For example, the resistance value of the 7th of Fig. 3 A touch-control processing unit joint 322 and the resistance value of the 1st fall in same range, then It can be determined that the 5th first electrode 121 is broken or loose contact, adjustment program can give a warning sign to user.Remove Outside this, the quantity of first electrode 121 and second electrode 122 is mostly even number design, if detect odd number root first electrode 121 or Second electrode 122, adjustment program can also give a warning sign to user.
In another embodiment, first electrode 121 can also be made to send drive signal in turn, then detects connected the Whether two electrodes 122 receive the drive signal of sensing.If a certain second electrode 122 of detecting does not receive corresponding driving letter Number, then it can be determined that the second electrode 122 is broken or loose contact.If taking turns to a certain first electrode 121 sends drive signal, And when detecting all second electrodes 122 and not receiving corresponding drive signal, then it can be determined that first electrode fracture or connect Touch bad.Conversely, the transmitting-receiving role exchange of first electrode 121 and second electrode 122 can also be subjected to checking detecting.
In one embodiment, in addition to Auto-Sensing, adjustment program can also allow user to be manually entered first electrode 121 With the circuit number parameter of second electrode 122.
Except Fig. 3 A and Fig. 3 B situation for misplacing with inverting, it is also possible to first electrode 121 occur and be connected to touch-control processing The joint of the second electrode of device 130, and second electrode 122 is connected to the feelings of the first electrode joint of touch-control processing unit 130 Condition.For example it is 20 but in general, the quantity of the first electrode 121 and second electrode 122 on touch control screen 120 is different: 30.If foregoing circuit resistance detects 30:20, then it is appreciated that there occurs first electrode 121 and the misconnection of second electrode 122 Situation.Touch-control processing unit 130 can reset connection network or multiplexer so that both can use software or firmware mutual Change, and electronic installation 100 need not be taken apart and readjust circuit.
In one embodiment, it is above-mentioned when the wiring connecting test of first electrode 121 and second electrode 122 has no problem Mutual capacitance scanning implementing result can save as a reference value.
In one embodiment, adjustment program can make touch control screen 120 give a warning information, it is desirable to user with finger, External conductive object or passive type Pointer contacts touch control screen 120.Because external conductive object can be the electromagnetic interference in the external world Signal pours into the first electrode 121 of touch control screen 120 and second electrode 122, thus touch-control processing unit 130 can at this moment, The frequency scanning of interference signal is carried out by first electrode 121 and/or second electrode 122.
For example, touch-control processing unit 130 can adjust the driving letter for sending N kind different frequencies when mutual capacitance is detected Number.When a certain or some kind of frequency people having the same aspiration and interest of electromagnetic interference signal caused by external conductive object and the N kind drive signals When, can be by more serious electromagnetic interference if touch-control processing unit 130 sends the drive signal of the people having the same aspiration and interest.Therefore touch-control processing dress 130 are put one by one to receive the signal of N kind frequencies when outside shaping claviform contacts touch control screen 120, find out interference Less serious at least one frequency, to use at least one less disturbed frequency in follow-up mutual capacitance detecting.
As shown in figure 4, it is the schematic flow sheet according to the detecting interfering frequency method of one embodiment of the invention.In step In 410, adjustment program makes the certain point that touch control screen 120 prompts user to make external conductive isoelectric membrane touch control screen 120.Connect , at step 420, whether touch-control processing unit 130 first can contact touch-control with mutual capacitance detecting external conductive object Screen 120, if having contacted, measure the interference signal intensity of the multi-frequency signal of driver.In step 430, touch Control processing unit 130 and store the most weak at least one frequency of interference signal, drive signal is sent when being detected for follow-up mutual capacitance When use the frequency.
In one embodiment, adjustment program can allow user to watch frequency set at present, decide whether that unlatching is changed Frequency function, and adjust the frequency hopping sensitivity (that is, determining to change the interference signal intensity value of frequency) of each frequency.User is also Frequency can be voluntarily selected, then tries out mutual capacitance detecting function, the interference experienced suffered by any frequency is minimum.
Previous Fig. 3 B are returned to, in wiring it is possible that the situation of joint anti-plug., can be with Fig. 4 step 420 Using the certain point position for prompting user to press, to detect both of these case.In a certain example, first electrode 121 is shared 20, and second electrode 122 shares 30.It is assumed that in step 410, the point for prompting user to press is located at the 5th first electrode Near 121 and the 10th second electrodes 122.And among step 420, the position received is in the 16th first electrode 121 and the 10th second electrodes 122, then may determine that the wiring of first electrode 121, there occurs anisotropy.Touch-control processing unit 130 can store the setting that direction inverts, by the 20th first electrode joint in turn as the 1st first electrode joint, 1st first electrode joint is as the 20th first electrode joint.Similarly, if the situation that second electrode 122 inverts, It can be reset according to the above-mentioned practice.Touch-control processing unit 130 can reset connection network or multiplexer, make Obtaining joint direction can use software or firmware to exchange, and need not take electronic installation 100 apart and readjust circuit.
In one embodiment, after touch-control processing unit 130 searches optimal or preferable driving signal frequency, then adjustment Program can make the display of touch control screen 120 poster that do not touch.Detecting no external conductive isoelectric membrane touch control screen Afterwards, the characteristic for each bar touch control electrode that can be directed to touch control screen 120 carries out adjustment setting.The applicant was previously applying United States Patent (USP) case 13/545,291,13/896,487,15/241,552, and its related various countries' application case, take off The detailed practice of these adjustment settings is revealed.Touch-control processing unit 130 can perform correlation detecting and setting procedure, so as to It is follow-up to carry out using these parameters during touch-control processing, particularly give at the AFE(analog front end) corresponding to each first electrode 121 The drive signal transmitting of part is managed with receiving parameter.
In one embodiment, adjustment program can also make touch control screen 120 show four points, and this is sequentially clicked by user Four points, to draw correction equation sequence group of the screen display point with touch point.The applicant is in the United States Patent (USP) previously applied Case 14/140,795, and its related various countries' application case, have disclosed the detailed practice of correction.Touch-control processing unit 130 can perform the detecting of correlation and aligning step, to use these correction parameters when subsequently carrying out touch-control processing.
Among adjustment more than, adjustment program or touch-control processing unit 130 have been directed to the hardware setting of touch control screen 120 Detected, detected also for the electromagnetic interference of environment where user.In one embodiment, at adjustment program or touch-control Reason device 130 can also be detected to the personal habits of user.As shown in figure 5, adjustment program can make touch control screen 120 Show rectangular area, ask user with finger or stylus in this region constantly to draw the gesture of rectangle clockwise.
Due to everyone for the touch-control feel of contact panel have it is light have a weight, radian change during turning has with translational speed Institute's difference.Therefore, everyone use habit can be directed to and carries out adjustment.In addition to the example shown in Fig. 5, the applicant exists The United States Patent (USP) case 15/016 previously applied, 788, and its related various countries' application case, can be as implementation here Example.
In one embodiment, adjustment program can allow user voluntarily to input the height of detecting sensitivity, be detectd to adjust Survey the height of the threshold value of touching signals.If user operationally has touch-control insensitive or excessively sensitive caused malfunction Make, can voluntarily adjust.
In one embodiment, adjustment program can allow user voluntarily to input the length and width dimensions of touch control screen, and input The touch-control fingers number that touch-control processing unit 130 is at most supported.Because the computing resource of touch-control processing unit 130 is limited , if it is possible to supported touch-control fingers number is reduced, then may increase the touch event reporting rate of unit interval.
Fig. 1 embodiment is returned to, among typical mutual capacitance touch-control sensing process, includes following operation sequence piece Section.The drive circuit of the touch-control processing unit 130 provides drive signal to a first electrode 121.Then, touch-control processing dress The sensing circuit for putting 130 passes through the measurement signal of at least one second electrode 122.Drive signal can be sent out along the first electrode 121 Go out, then sensed by the second electrode 122.Then, the processor of the touch-control processing unit 130 is carried out to the signal measured Processing, when having the external conductive object proximity first electrode 121 or the second electrode 122, can detect measurement signal It is abnormal, determine whether the proximity position of the external conductive object.
What first electrode 121 and second electrode 122 on touch control screen 110 were formed is a kind of resistor capacitor circuit (RC circuit).If when touch control screen 110 are made, shape, the thickness of first electrode 121 or second electrode 122 And/or line footpath not as expected when, then the resistor capacitor circuit that is formed electrically just and expected difference.Although modern Touch-control processing unit 130 has been able to further handle a small amount of variation, when not excessive variation differs too many, will result in sense The deviation of survey.Therefore, one of problem to be solved by this invention, it is to detect the first electrode 121 or the on touch control screen 110 Whether two electrodes 122 have the major imperfections on making.It is touch control screen manufacturer or touch-control that detecting error can be differentiated whereby The responsibility of processing unit manufacturer.Furthermore, when discovery has flaw, which bar first electrode can also detect is 121 or second electrode 122 there is flaw, so as to as the self-criticism and improvement in manufacture craft.
Refer to shown in Fig. 6, it is the partial enlarged drawing of touch control screen 120.In the touch control screen 110, comprising a plurality of First electrode 121 and two second electrodes 122 and 622.These first electrodes 121 and second electrode 122 are all leading by rhombus Electric piece is formed by connecting.It will be understood by those skilled in the art that can have with second electrode to first electrode miscellaneous Shape is formed, and Fig. 6 is an illustrative examples.Exemplified by lifting second electrode 122, there is lapping circuit between rhombus conducting strip 601 are connected.Because the line width of lapping circuit is thinner, therefore the resistance of second electrode 122 largely depends on the line of lapping circuit 701 It is wide.The line width of the lapping circuit part of second electrode 622 is suitable with second electrode 122, therefore the resistance value of second electrode 622 and the The resistance value of two electrodes 122 is suitable.But because second electrode 622 contains the conducting strip 624 of a non-rhombus, itself and first electricity Capacitance between the conducting strip of pole 121 is different.So two second electrodes 122 differ with 622 capacitance resistance effect, result in Above-mentioned sensing deviation.
Refer to shown in Fig. 7, it is the thin portion schematic diagram for betiding the mutual capacitance sensing on touch control screen 120.The touch-control One first electrode 121 of screen 120 forms four crosspoints with least four second electrodes 721~724.Touch-control processing dress Put 130 and drive signal is sent by first electrode 121, sensed while being received by this four second electrodes 721~724 Drive signal.
